margin-block-start, margin-block-end not highlighted

[xmedeko]

To reproduce:

ul
    margin-left 0
    margin-block-start 0
    margin-block-end 0

Current behavior:

While margin-left is highlighted as known property (red), margin-block-start, margin-block-end and many other newer CSS properties are not highlighted as known properties.

Note: margin-block-start, ... are offered in VS Code intellisense properly, even with a tooltip.

Expected behavior:

margin-block-start, margin-block-end should be highlighted the same way as other known properties (i.e. red).
